I am coming from a Smartthings hub Im not really knowledgeable about networking and I dont really know where im going wrong.
Thank you for any and all help,
 
I have done a fresh install attempted to run scripts and I get this.
Code:
root@pve:~# bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/tools/pve/post-pve-install.sh)"
curl: (6) Could not resolve host: raw.githubusercontent.com
root@pve:~#

I read that it is usually the DNS I set it to 8.8.8.8 attempted to ping google
Code:
root@pve:~# ping google.com
ping: google.com: Temporary failure in name resolution
root@pve:~#

I have tried to look at my network settings I watched some videos I just cant figure out which of my network settings is wrong.
Is there something simple I could be overlooking? I liked the idea of doing Proxmox so I could also run PiHole as well as HA if i cant figure this out should I just do HAOS?
 
Thanks
Code:
root@pve:~# ping 8.8.8.8

# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Try to get a temporary DHCP lease like this and share the output. The first command gets a lease and the second restores the original configuration again.
Bash:
# For PVE 8 / Debian 12
ifdown vmbr0; dhclient -v
dhclient -r; ifup vmbr0

# For PVE 9 / Debian 13
ifdown vmbr0; dhcpcd -d
dhcpcd -k; ifup vmbr0

Can you reach your gateway? I.e. does
Code:
ping 192.168.1.1
work?
it did not

I have it allocated it just gave me a list of ips in my DCHP range
 
I changed a setting and lost access to it did a fresh install set gateway correctly and it is now working I appreciate yalls help.
